The Dream of Styleguide Driven Development

Getting performance right is hard, even when we have the luxury of starting our apps from scratch. It’s even harder when the ideal crashes headlong into reality, and we need to improve the performance of existing apps, as is so often the case. In this workshop, Sara Vieira and Jason Lengstorf will lead you through the process of:

 <ul>
 <li>Assessing an existing React app</li>
 <li>Diagnosing performance problems</li>
 <li>Prioritizing the fixes that will make the biggest impact</li>
 <li>Implementing performance fixes</li>
 </ul> 

 During this full-day workshop, you’ll learn advanced techniques for improving the performance of React apps, including:
 
 <ul>
 <li>Lazy loading resources & components (including React.lazy and Suspense)</li>
 <li>Leveraging Service Workers for performance</li>
 <li>Seamlessly preloading and prefetching assets</li>
 <li>Automatically optimizing images and fonts</li>
 <li>Mitigating the performance impact of third-party scripts</li>
 <li>Code splitting and bundle optimization</li>
 <li>Using psychology to make your app feel faster than it actually is</li>
 </ul> 
 
 By the end of the workshop, you’ll be able to diagnose performance problems and solve them with a combination of modern and time-tested performance techniques. You’ll also learn how to weigh the trade-offs of implementing fixes to ensure that both your apps and your teams perform well. The tools added to your toolbox will continue to serve you, your team, and your users for years to come.
